• Conversion ratio of dedicated instructions
The following table shows the conversion ratio when changing the programmable controller type of
the AnSCPU dedicated instructions to the QCPU.
The automatic conversion is applied to the instructions of which equivalent functions and instructions
exist in the change destination programmable controller.
Some instructions are not converted for the following causes.
Refer to Section 7.2 Instruction Conversion to change the program manually.
(1) The change target programmable controller does not have the equivalent functions and
instructions.
(2) Instructions to specified modules cause to change the module and buffer memory configuration.
(3) Multiple instructions with the same name and argument exist.
(4) The conversion causes a mismatch in the instructions.
